Microsoft Dynamics NAV 2013 R2 introduced the concept of interactive column sorting on list pages such as Sales Lines or the Chart of Accounts. This is a very handy feature, but at times, an errant click can send the data into a sort that you can’t get back to unless you close the page and re-open it. For example, the default Sort on Sales Order lines is “Document Type,” “Document No.,” “Line No.,” and since “Line No.” isn’t by default displayed, you can’t get back to the default sort.
